Mechanical Engineering
Evaluation of an innovative system integrating energy
storage and electrical discharge during peak hours directly to
the grid. The system uses adiabatic underwater air
compression combined with thermal storage and discharge
by means of a linear dynamic pneumatic system.
•Working hours fluctuate
constantly for the various
consumers (e.g., domestic,
industrial and so on).
• Nuclear, hydroelectric, and
fossil-based traditional
power plants are not easily
shut down or put on hold.
Energy
Demand
• power plants are kept
operational during the
night and they are
likely to produce
excess power.
• Energy storage solution
for renewable energy
power production
excess power during
operational time
.
Excess Energy
• The stored energy offers a
solution for managing peak
loads and reducing output
during normal daytime or
for maintenance backups..

Research and feasibility of under water compressed air system (UWCAES) :
•
Study on types of CAES.
•
Comparison of the existing UWCAES,
and understanding of their pros and
cons.
•
Analysis of compressed air as a
working fluid at each subsystem, and
the variations in its properties.
•
